Abstract: This paper develops a novel empirical strength criterion and proposes a manifold method for fracture initiation and propagation. First, to investigate the influencing factors of fractured rock mass strength, a set of ...

Abstract: Prediction of rock mass strength is important for estimating stability in rock engineering projects. In this paper, a novel strength criterion was proposed to determine the strength of a jointed rock mass subjected to a ...

Abstract: This paper presents an experimental study in which molded gypsum specimens with different crack geometries (T-shaped and X-shaped cross crack) were tested in biaxial compression. Crack propagation and failure behaviors ...

Abstract: Rock mass subjected to acidic groundwater corrosion may cause great property alteration. In this work, the effects of microstructure on change of the pore structure and mechanical property under acid corrosion were ...
